Substantiation of Structure and Basic Design Parameters of Devices for Orienting Powered Support Relatively to Face Conveyor in Formation Plane

Abstract

One of the reasons for the inefficient use of powered support due to the dislocation of the direction of movement of the powered support unit relative to the face conveyor in the formation plane is identified. The substantiation of the structural parameters of the connection of the eye of the cap of pile of the movement mechanism of the linear powered support unit with the eyes of the face conveyor was carried out. The dependence of the angle of rotation of the eye cap of pile of the movement mechanism in the eyes of the face conveyor is determined. The necessity of installing armored powered support unit equipped with rod transfer mechanisms is substantiated in the lower part of the breakage face. The developed design of the movement mechanism of the anchor sections is of the same design as the movement mechanism of the linear powered support unit and differs only by the cap of pile. The cap of pile of the anchor sections has two spaced lugs that are pivotally connected through axes to the eyelets of the face conveyor. The proposed mechanism for moving the anchor sections provides for the directional movement of powered support which significantly increases the efficiency of the complex.
